Abstract

Disclosed is a patch antenna in which coupling gaps are formed between a lower patch and feed pins so as to maximize the performance of the antenna. The disclosed patch antenna comprises: a base layer; an upper patch disposed on the upper surface of the base layer; a lower patch disposed on the lower surface of the base layer; and feed pins passing through the base layer, upper patch, and lower patch, wherein the feed pins are spaced from the upper patch and thereby form coupling gaps.

Claims

exact text as granted — not AI-modified
1 . A patch antenna comprising:
 a base layer;   an upper patch disposed on a top surface of the base layer;   a lower patch disposed on a bottom surface of the base layer; and   a feeding pin penetrating through the base layer, the upper patch and the lower patch,   wherein the feeding pin is isolated from the upper patch so that a coupling gap is formed.   
     
     
         2 . The patch antenna of  claim 1 , wherein:
 wherein a feeding hole through which the feeding pin penetrates is formed in the upper patch, and   wherein the feeding pin is isolated from the feeding hole formed in the upper patch so that the coupling gap is formed.   
     
     
         3 . The patch antenna of  claim 1 ,
 wherein a width of the coupling gap is 0.5 mm or more and 1.5 mm or less.   
     
     
         4 . The patch antenna of  claim 1 ,
 wherein the feeding pin comprises:   a first feeding pin penetrating through a third feeding hole formed in the upper patch; and   a second feeding pin penetrating through a fourth feeding hole formed in the upper patch.   
     
     
         5 . The patch antenna of  claim 4 ,
 wherein the coupling gap comprises:   a first coupling gap formed in an isolated space between the first feeding pin and the third feeding hole; and   a second coupling gap formed in an isolated space between the second feeding pin and the fourth feeding hole.   
     
     
         6 . The patch antenna of  claim 5 ,
 wherein a width of the first coupling gap is identical with a width of the second coupling gap.
